Julie Ezold is a nuclear engineer at Oak Ridge National Laboratory. She directs a project in the Radiochemical Engineering Development Center that uses the High Flux Isotope Reactor to create californium-252. In this interview, Ezold describes the project and how the Reactor is used to create californium-252 and other elements. She explains the importance of sustained research into element and isotope production in the future, and also provides insight into the practical application of this work. Ezold also explains how she became interested in science as a teenager, and what it is like to be a woman scientist working on nuclear issues.
